Image Comparer ™ this is a utility for search for similar pictures... Color gamut and different resolutions have little effect on the quality of the comparison. Image Comparer ™ will find all similar images even if one of them is in JPEG format and the other in standard Windows bitmap format. Since version 3.3, Image Comparer has learned to highlight differences in compared images, and since version 3.7 the program has been optimized for use with modern multi-core processors.

If you have a large collection of images in various formats, then you know how difficult it is to remember everything and delete the same images. But what if they are the same, but of different quality (resolution, compression ratio)? We provide you with an easy solution to this problem. Image Comparer ™ automates the process of finding similar images. Note that Image Comparer ™ searches not only for completely identical images, but also for simply similar images! As a result of the comparison, you get a list of pairs of images with a percentage of similarity. 100% means the images are exactly the same, then you can remove the duplicate images with the worst quality with just two clicks!

Supported image formats: RAW, JPEG, J2K, BMP, GIF, PNG, TIFF, TGA and others.

Surely you have a large database of photographs. And it so happened that you are looking through photographs from this database and there is a feeling that some photos are repeated? Manually look for duplicate photos- long, painful and stupid. I agree with those who say that this is simply a useless exercise, because photos do not take up so much hard disk space, however, to have well-ordered catalog of photos still want to. And this article would not exist if there was no programmatic way find duplicate pictures, so it won't be difficult for you to do it!

To find duplicate photos, you can use the program AntiDupl.NET... The program is absolutely free, supports the main graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF ​​and ICON, has a Russian interface. And actually it perfectly fulfills its main function, the search for duplicates.

From words to deeds. By downloading, from the link above, the latest version of the program AntiDupl.NET, you will receive a self-extracting archive on your computer. Double-clicking on it, you will see the following window, where we will be asked to choose a location to unpack the files. Unpack it directly to your desktop.

As a result, in the place that you indicated, a folder with the program, ready to work, will appear. Without thinking for a long time, we launch it. Initially, everything we have there is in English. To see the native Russian language, do the following: Click View - Language - Russian.

In Options, you can add a checkmark: Search for rotated and mirror duplicates - as often some identical photos are simply inverted.

Next, select the folder that contains the photos and which supposedly contains duplicates. To do this: Click on the folder icon - the Paths window appears - click to add a directory - select the desired folder - click OK. If you need to search not in one, but in several folders, do this operation again.

To start the search, click on the green play icon.

As a result, the program will display a list of duplicate images. Then you can either delete both or one of the duplicates.

If in the options set Take into account the size of pictures and Take into account the type of pictures, then the program will find duplicates of only one size and only in one extension, respectively. I would not recommend displaying these jackdaws, since you often come across the same pictures, only of different sizes.

Find Duplicates in Large Photo Collections

Image Dupeless 1.6.3 (Russian) is designed to search for similar images (duplicates) in large collections. Supported graphic files in formats JPEG, GIF, BMP, PCX, PNG, TIFF, PGM, WMF, EMF, EPS, PSD, ICO. The comparison is based on the content of the images regardless of their size, format, resolution, etc.
There are advanced possibilities of cataloging the galleries available on the CD and further off-line work with them. At the same time, comparing newly received images with those already available in the gallery takes much less time than a full rescanning of the gallery itself, and possibly even in the absence of the CD with the gallery itself. There are internal tools for comparing, deleting, moving and updating files, changing the binding of the gallery root directory.
Key features:
- a unique opportunity to merge a series of images, based on information about the similarity;
- optional ability to store thumbnails of images and work in off-line mode;

- the ability to search the gallery for images similar to the given one;
- the ability to save the results of the search for duplicates;
- the ability to quickly update the gallery, bringing it into line with the files on the disk without re-reading (for example, after moving the gallery to a new location);
- the ability to set a user-defined list of unlike images (for example, when you do not want to delete some very similar pairs and do not want them to appear in the list of found duplicates after each new comparison);
- the ability to automatically mark "bad" duplicates for further deletion, according to user-specified conditions;
- visual and convenient presentation of duplicate search results;
- the ability to vary the performance / convenience ratio by changing the parameters;

Good day.

Statistics are unforgiving things - many users have dozens of copies of the same file (for example, a picture, or a music track) on their hard drives. Each of these copies, of course, takes up space on the hard drive. And if your disk is already "crammed" to the eyeballs, then there can be quite a lot of such copies!

Cleaning duplicate files manually is not a gratifying thing, which is why I want to collect in this article programs for finding and removing duplicate files (moreover, even those that differ in file format and size from each other - and this is a rather difficult task !). So…

List of programs for finding duplicates

1. Universal (for any files)

Search for identical files by their size (checksums).

By universal programs, I mean, those that are suitable for finding and deleting duplicates of any file types: music, movies, pictures, etc. (below in the article for each type will be given "their" more accurate utilities). Most of them work according to the same type: they simply compare the file sizes (and their checksum), if there are files with the same characteristics among all files, they show you!

Those. thanks to them, you can quickly find full copies (i.e. one to one) of files on the disk. By the way, I also note that these utilities work faster than those specialized for a specific file type (for example, image search).

DupKiller

I put this program in first place for a number of reasons:

• supports just a huge number of different formats in which it can conduct searches;
• high speed of work;
• free and with Russian language support;
• very flexible setting of duplicate search (search by name, size, type, date, content (limited)).

Duplicate Finder

This utility, in addition to searching for copies, also sorts them as you please (which is very convenient when there are an incredible amount of copies!). Also add to the search capabilities byte comparison, checksum matching, deleting files with zero size (and empty folders too). In general, this program does a pretty good job of finding duplicates (both quickly and efficiently!).

Those users who are not familiar with English will feel a little uncomfortable: there is no Russian in the program (perhaps it will be added after).

Glary utilites

In general, this is not just one utility, but a whole collection: it will help to remove "junk" files, set optimal settings in Windows, defragment and clean up the hard drive, etc. Including, this collection contains a utility for finding duplicates. It works relatively well, so I will recommend this collection (as one of the most convenient and universal - as they say for all occasions!) Once again on the pages of the site.

2. Programs for finding duplicate music

These utilities will be useful to all music lovers who have a decent collection of music on their disk. I draw a fairly typical situation: you download various collections of music (100 best songs of October, November, etc.), some of the compositions are repeated in them. Not surprisingly, having accumulated 100 GB of music (for example), 10-20 GB can be copies. Moreover, if the size of these files in different collections were the same, then they could be deleted by the first category of programs (see above in the article), but since this is not so, then these duplicates are not found by anything other than your "hearing" and special utilities (which are presented below).

M usic Duplicate Remover

The result of the utility.

This program differs from the rest, first of all, its quick search. She searches for duplicate tracks by their ID3 tags and sound. Those. she will, as it were, listen to the song for you, remember it, and then compare it with others (thus, she does a huge amount of work!).

The screenshot above shows her work result. She will present her found copies to you in the form of a small plate, in which a number in percentage of similarity will be assigned to each track. In general, it is quite convenient!

A

Found duplicate MP3 files ...

This utility is similar to the above, but it has one definite plus: the presence of the most convenient wizard who will guide you through the steps! Those. the person who first launched this program will easily figure out where to click and what to do.

For example, in my 5000 tracks in a couple of hours, I managed to find and delete several hundred copies. An example of the utility's operation is shown in the screenshot above.

3. To search for copies of pictures, images

If we analyze the popularity of certain files, then the pictures, perhaps, will not lag behind the music (and for some users, they will be overtaken!). It's hard to imagine working on a PC (and other devices) without pictures! But finding pictures with the same image on them is quite difficult (and long). And, I must admit, there are relatively few programs of this kind ...

Image Comparer

I have already mentioned this program on the pages of the site. It is also a small program, but with pretty good algorithms for scanning pictures. There is a step-by-step wizard that starts when you first open the utility, which will guide you through all the "thorns" of the first setup of the program to search for duplicates.

By the way, below is a screenshot of the utility's operation: in the reports you can view even small details, where the pictures are slightly different. In general, it is convenient!

4. To search for duplicate films, video clips

Well, the last popular file type that I would like to focus on is video (movies, videos, etc.). If sometime before, with a 30-50 GB disk, he knew in which folder where and which movie it takes how much (and they were all in all counts), then, for example, now (when the disks became 2000-3000 GB and more) - they are often found the same videos and movies, but in different quality (which can take up a lot of hard disk space).

For most users (yes, in general, for me 🙂), this state of affairs is not necessary: ​​it just takes up space on the hard drive. Thanks to a couple of utilities below, you can clean up duplicate videos from your disk ...

Duplicate Video Search

A functional utility that quickly and easily finds a similar video on your disk. Here are some of the main features:

• detection of video copies with different bit rates, resolutions, format characteristics;
• auto-selection of video copies with poorer quality;
• identify modified copies of videos, including those with different resolutions, bit rates, cropping, format characteristics;
• the search result is presented in the form of a list with thumbnails (showing the file characteristics) - so you can easily choose what to delete and what not;
• the program supports almost any video format: AVI, MKV, 3GP, MPG, SWF, MP4 etc.

The result of her work is shown in the screenshot below.

Good day!

I think that many users have tens (or even hundreds) of gigabytes of pictures, wallpapers, videos, music and other files on their disk. And I must note that in different directories (in collections of wallpapers, for example) there can be quite a lot of copies (duplicates). Often, after deleting them, it is possible to free up several gigabytes of space on the HDD!

There are special programs and utilities for finding duplicates. They are ways to scan your hard drive (s) in a relatively short time and present everything the same to you. Further, as a rule, you will only have to mark with checkboxes what to delete - and voila, the place is cleared!

In this article, I will present a few of these "cleaners" that will help you free up space on your hard drive. So...

Addition!

Top 14 programs for finding duplicates (identical files)

Universal (search for any files)

Universal programs for finding duplicates are suitable for working with any files: documents, photographs, videos, etc. As a rule, their work is based on finding files of the same size and checksum. Those. these programs look for exact copies that match 100%!

Due to this, their speed of operation is quite high. However, they cannot find, for example, almost identical pictures, which are saved in different formats and with excellent resolution. To do this, you must use a special. The software I recommend below ...

Computer accelerator

This utility with a self-explanatory name from Russian developers. In general, it is designed to remove junk files, fix errors in the registry, control the state of startup, etc., but there are special tools in its tools. a module that allows you to find duplicate files. See screenshot below.

So, after starting this function, you will be prompted to specify the folders (which will be analyzed), and click the search button. After a while, the program will present you with all the duplicates found - all that remains is to delete the "unnecessary".

For example, I analyzed my Music folder and found out that I have 311 mp3-takes of 2.65 GB. Moreover, this folder is not that big for me. The result is shown in the screenshot below.

Of course, if you have a lot of collections on the disk (pictures, music, etc.), the amount of free space can be much larger!

Note: the free version of the program works in full mode for 5 days.

CCleaner

One of the most famous PC cleaning utilities. However, not many users know that there is a duplicate search function in its arsenal (and, moreover, a very good function!).

To open this option: you need to download the latest version of the program, in the menu "Service" choose "Search for duplicates" , specify the settings and click the button "To find" .

Note that the search is fast enough, you can filter files by their size, name date. You can also manually set specific drives (folders) to search. All in all, quite convenient!

Glary Utilities (Glary Duplicate Cleaner)

Glary Utilities is a great set of utilities for all occasions. Contains all the most essential tools for cleaning, maintaining and optimizing Windows. I have repeatedly recommended this complex on the pages of my blog ...

It has one small utility in its firmware arsenal. Glary Duplicate Cleaner. It allows you to quickly find duplicates of various file formats: TXT, RAR, ZIP, MP3, WAV, AVI, JPG, BMP, etc. (in general, all the most popular ones are definitely there, see the screen below).

Configuring Scan Settings / Glary Duplicate Cleaner

There is also a small filter with search criteria: by name, size, time. There is an option to skip files of a certain size (for example, you can skip files that weigh less than 100 KB).

Note that the package Glary utilities free, and fully translated into Russian. In general, the score is 5 on a 5-point scale!

AllDup

This is a small free utility to scan all your drives very quickly and remove any duplicate files. The developers note that their search algorithm is 10-30% faster than other similar products.

Personally, I have not tested the speed, but I would note the following: the utility works in all Windows 2000, XP, 7, 8, 10 operating systems (this is a kind of advantage!).

After the search, the AllDup utility will present you the results: you can familiarize yourself with each duplicate and delete it directly from the program interface. Comfortable!

Duplicate File Finder

Free tool for cleaning disks from duplicate files. The program compares the files on the specified disk (directory) by byte. There are standard filters: file extension, file name, creation date, and size.

The search result (an example is shown in the screenshot above) can either be viewed in the program itself (and make a decision), or you can export it to HTML, CSV and TXT files. By the way, I would note that the program has a fairly convenient viewer that allows you to view a picture, text, video.

Total commander

This famous commander (a nice replacement for explorer) also has a file search function. To open it - click on the "magnifying glass" icon in the top menu of the program (see the screen above).

Of course, there are not so many opportunities here, but nevertheless ...

To search for photos, pictures, graphics

These programs can search not only by the size (checksum) of the file, but also by the contents of the picture. For example, you have several identical desktop wallpapers in two different folders (but these pictures have different sizes and resolutions).

So, the programs given above would not find these duplicates, since they "cannot" appreciate what is shown in the pictures. In this case, you must use the special. tools (about them below) ...

Image Comparer

This is a very small utility that specializes in finding similar images. I note that it compares not just the size, but what is shown in the picture (see the screen above). All popular image and photo formats are supported: RAW, JPEG, J2K, BMP, GIF, PNG, TIFF, TGA, etc.

After the search, you will be presented with a list of duplicates: by going through it, you can view all copies and delete those that you do not need. What's interesting: the program shows you the percentage of similarity of certain pictures (the difference between them is highlighted when viewed with squares).

Cons: if you specify a large disk (several terabytes) - the program will take a very long time to scan. Before using it, I recommend that you go through the pictures using coarser tools. (for example, CCleaner, AllDup, etc., see above).

DupeGuru Picture Edition

A very simple utility designed to quickly search for identical pictures. Note that similar pictures will be found even if they have different formats (for example, JPG and Tiff as in the screenshot above).

Benefits of the utility:

• visual comparison of pictures;
• the program is completely free;
• simple interface made in the style of minimalism;
• Russian language support;
• the ability to export search results;
• support for all the most popular versions of Windows XP, 7, 8, 10.

ImageDupeless

Program ImageDupeless allows you to find duplicate pictures, regardless of the file size, format, resolution and other characteristics (it seems to "look" for you all the pictures and find similar ones).

Also, the program has a very interesting function for burning images to CD discs (creating a kind of CD galleries).

Note: to save time, compare newly received pictures with the existing gallery (this way you will save a lot of time, since a full scan of all images on the disk takes much longer than already searching in the created gallery).

Comparison result: please note that the resolution and size of the pictures are different!

Visual Similarity Duplicate Image Finder

The program uses advanced algorithms to compare graphic images in pictures and photographs. Thanks to this, it is possible to find similar and identical pictures, even if they have a different format (GIF, PNG, JPG, etc.) and resolution.

Note that the user has an option for specifying a similarity attribute (i.e., you can ask, say, to find only those pictures that are 95% similar to each other).

After searching: you can view all found duplicates and manually delete all unnecessary ones. By the way, the program places 2 identical images next to each other (see example above) so that you can clearly see the difference. Very convenient!

To search for audio and video files

Audio Comparer (Electronic Ear)

Audio Comparer - the program will listen to almost 300 tracks in 10 minutes.

Audio Comparer is not as simple an application for finding duplicates among music files (MP3, MP2, MP1, WMA, AIF, WAV, WavPack, FLAC, APE, AAC and OGG) as it might seem at first glance ... It is " listens to "music and compares the tracks with each other according to a special algorithm: the comparison is made by the audio track, and not by the size or name of the file (as is done in many other analogs)."

Due to this, the same tracks can be found even if they are saved in different formats. Audio Comparer is a kind of electronic ear that can listen to all your music very quickly.

Note that there are quite a few such programs, so each deserves special attention! I recommend to meet you!

DupeGuru Music Edition

Note! Music Duplicate Remover supports the following audio formats: MP3, WMA, OGG, FLAC, APE, WAV.

Note that the program uses a unique "impression" technology (ie, a kind of "electronic eye"), which allows you to find similar videos, even if they are saved in a different format, they have a different resolution and they are compressed with a different codec.
